Off to the junk yard....might spot a caddy 4t60 with the 2.53:1 final drive ratio and 0.7:1 over drive, that would give me 1350 rpm at 65 mph.

i don't know how well the 3.1TBI will take to that kind of gear reduction... that is a LOT of vehicle to move with 120HP/170TQ with that kind of gearing.... you might run into enough throttle to hit PE just cruising at a steady speed in 4th gear.
